# Nepot-filter

Nepot-filter is a special tool developed by Yandex for filtering of the sites which practice promotion of the sites with the help of nepot-spam (link exchange, link farms, etc.). Filtering by a nepot filter consists in a refusal to use the links from a spammer site. With the nepot filter the site is being indexed as usual, periodically the quotation index is counted again, but in the provisioning it is noticeably reducing.
